Unreal never looked better than this to me, even beats 227 imo.
Is a dx10 renderer so you must have a dx10 or dx11 capable card. Also, you must be on Vista or Win7 of Win8 for it to work. Also, will only work on a 226 (gold) install, not on 227.

Forgot to add that I use this guy's Dx9 renderer for UT and it works superb, http://www.cwdohnal.com/utglr/
Although I am using the same DX10 renderer in UT with great results
